0–100, higher is better. How it is calculated

Sauropods.win operates as a niche Mastodon instance dedicated to sauropod enthusiasts, providing a community-driven social media platform within the Fediverse. The website leverages the Mastodon 4.4.2 platform with modern web technologies such as React and JavaScript modules, hosted under Hover.com's domain services. The platform offers typical Mastodon features including user posts, profile directories, and public timelines, targeting a small but active user base. Security posture is solid with HTTPS enforced and domain transfer protections, though DNSSEC is not enabled and no advanced security policies are publicly disclosed. Privacy compliance is minimal with a basic privacy policy present but lacking cookie consent and terms of service. Business credibility is moderate given the community nature and lack of commercial presence. Overall, the site is functional, safe, and well-branded but could improve transparency and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website serves a specialized community within the social media landscape, focusing on sauropod appreciation. It operates as a small-scale, independent Mastodon server with approximately 90 active users. The business model is community and interest-driven rather than commercial. There is no indication of revenue streams or partnerships. The platform benefits from the open-source Mastodon ecosystem, which supports federated social networking. The lack of explicit business contact information and formal policies suggests a volunteer or hobbyist operation. Growth potential depends on community engagement and federation with other Mastodon instances.

Security posture

Security measures include HTTPS enforcement, domain status locks to prevent unauthorized changes, and use of a reputable registrar with privacy protection. However, DNSSEC is not enabled, which could expose the domain to DNS spoofing risks. No advanced HTTP security headers were detected in the HTML content. The absence of published security policies, incident response contacts, or vulnerability disclosure mechanisms limits transparency and preparedness. Forms appear standard with no visible security flaws, but no explicit mention of secure input handling or CAPTCHA. Overall, the security posture is adequate for a small community platform but could be enhanced with additional controls and disclosures.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security.
  2. Publish comprehensive privacy, cookie, and terms of service policies including GDPR compliance details.
  3. Add explicit contact information for security incidents and general inquiries.
  4. Implement and document a vulnerability disclosure policy and incident response procedures.
  5. Enhance HTTP security headers such as Content-Security-Policy and X-Content-Type-Options.

Technical notes

Notes

The website is built on Mastodon 4.4.2, utilizing React and modern JavaScript ES modules for frontend interactivity. The site loads multiple JavaScript bundles and CSS assets with integrity checks, indicating attention to resource integrity. Hosting is via Hover.com DNS services, with no CDN explicitly detected. Performance is moderate with responsive design and mobile optimization evident. Accessibility features are basic but present. SEO metadata includes Open Graph tags and descriptive meta tags. No analytics or tracking scripts were identified, aligning with privacy-conscious design. The technical stack is modern and appropriate for a federated social media platform.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
